TO AIiL WHOM' IT MAY CONCERN:

Be it known that I, EUGENE McDONNELL, of Baltimore, in th`\ccuntyofBaltimore, and State of Mary land, have invented an improved CottonCompressor; and I do hereby`\declare that the following is a full andexact descriptionv thereof, reference being had to the accompanyingdrawings, making part of this specification- 4 Figure 1 being a sideelevation of the compresser.

Figure 2 a .top view thereof. Lilte letters designate correspondingparts in both of the figures.

v The main object ofl my invention is to produce a cotton compresserwhich can be operated by horse power, and yet possess suilicient powerfor rapid compression. Another desidratum is to secure adequate strengthof parts againstthe immense strain to which it is subjected with simpleand economical means. l

v My compresser is an open one, 'se that-the'bale x can be had access toon all sides. The framework, which supports. the other parts, consistssimply of four posts, A A'A A, framed into a suitable hase, B. As this'frame is not subjected to all the strain of the 'compressonfit is notrequired to he so strong as otherwise it.

` must be. The part which receives the whole force of the compression,and mustr resist .the concentrated strain' thereof,is a set oflongitudinal iron beams, C C C C, placed horizontally at the upper partof -the framework, to thc postsA A of which' they are secured by strongbolts, mm, passing through the posts and beams., These beams are notonly of iron, hut are massive,'and placed verticallyedgewisdmsubstantially as represented. They become the fulcruui-blocksupon which the power levers II are supported from above, andagaiustwhich the bales are lcompressed upward from below, so that the powerfulforces of these vtwo actions are brought inte direct antagonism to cachother, andthatL through the mero compression of thesebeams,and'therefore littlc diable to have adestructve action upon them.The bolts m m, which pass through andconnect the posts,A A and beams CC, also serve as pivots on which the toggle armsjI. I I of-tlicpowerlevers vibrate. There are arms, L I3, both outsidcof the levers-andbetween them,- svo as'to multiply the strength and divide the strain asmuch as possible; and these likewise interwcavc with the beams C C for alike' purpose. The toggle arms are pivotod to the power levers by bolts,Z Z, as represented. The power 'leversI I, on opposite sides of' thepress,

' are keptfrom separating,and at uniform distance apart,connecting-bars,K K, and they are kept from approaching `by'guidestandards, D, which are braccd'a'pait by a cross-beam or beams, d.Friction-rollers, i

`li'fat tlleiupplerends of the levers, relieve thcfriction of thecontact with these guide standards. Thdpowcr levers liftthe follower Eof the press directly, by means of very strong wrought-iron bands orrods, M M, which are' attaehed'at the upper ends to the levers by bolts,le k, or the equivalent thereof, and at their-lower ends, to thefollower, by extending down around the ends thereof, substantially asshown in fig..1. The power of the vhorses is applied to the press bymeans'of a capstan, P, or its equivalent, and ach'ain, N, which extendsfrom the capstan first around pulleys, p p, attached vto the frame ofthe press near thebottom, then around pulleys, j j, respectively at theends of the levers I I, on opposite sides of the press, and is finallyattached by its two ends to staples, 'rt n, or their equivalent, on theframe of the press. The multiplication of power -by these ineens isimmense: first, the leverage of the capstan; then the doubling of thepower by the pulleys jj; then the leverage of the levers I I, andfinally, the toggle action of the toggle arms with the levers, the samerapidly' increasing as the toggles` approach a straight line, asrequired bythe increasing resistance of the compressed bales. Thus apower suicient to compress a bale-of cotton tothe desired extent ispossible with a single horse, and the work is done very expeditiouslypress is adapted to diercnt sizes of bales by adjusting the bed G. Iaccomplish the adjustment bysthc insertion of solid blocks or timbers,H, of different thickness, between the movable bed G and thefulcrum-beams C C. The bcdGr is moved up and down by means of cords orchains,

` 's s, lifting at its lfour corners, then passing up over pulleys, tt,aud'iinallywinding around a windlass, S, which Yis turned by a cord,'T,passing thence over u pulley, c, to a ratchet shaft and crank, R. Thefollowup-E is suitably strengthened by ribs, c, underneath.-

What I claim as my invention, and desire to secure by Letters Patent,is'- v A cotton-bale compresser vprot'ided with the. following. parts:Fulcrum-beams C C, power levers I I, toggle arms L 4L, lift-ingro'ds MM, rising follower E,'adjustable uoper bed G, and v`the whole driven 'bymenus of a pulley cliain, N, and capsAtan '1), `or its equivalent, towhich the power of liorses mayy be applied, aller-ranged and operatingsubstantially as and for the purpose herein specified.'

I also clnimtho combination of the fnlcrum-beams C C, arranged betweenalle follower Eend powjerlevex's I I, through means of the toggle arms LL v:md litingmmsM M', substantially as herein set forth.

I also claim the adjustment of the bed G, by means of tllelblocks ortimbers H, andthe means 'described, or tlxe `equivalent thereof, forraising and lowering the bedysubstantially as described. v I

. I also claim the alternate arrangement or interweexing-of thefulcrumbeams C C'zmd toggle arms L L, as
